请问一下网格处理时系统怎么计算近似全局尺寸的

mikevenus

大家好,我想问一下网格划分撒种子时候有一个近似全局尺寸,根据每个零件大小的不同,会有不同的值,系统是怎么计算这个值的,我有一个脚本需要根据零件尺寸大小自动撒种子,不知道这个值该怎么取.谢谢大家
p.seedPart(size=2.0, deviationFactor=0.1, minSizeFactor=0.1)

我查了文档,里面也没有说

1. 30.2.23 seedPart(...)
   
2. 
   
3. This method assigns global edge seeds to the given parts.
   
4. 
   
5. Required arguments
   
6. 
   
7. regions
   
8. A sequence of Part objects specifying the part instances to seed.
   
9. 
   
10. size
    
11. A Float specifying the desired global element size for the edges.
    
12. 
    
13. Optional arguments
    
14. 
    
15. deviationFactor
    
16. A Float specifying the deviation factor , where  is the chordal deviation and  is the element length.
    
17. 
    
18. minSizeFactor
    
19. A Float specifying the size of the smallest allowable element as a fraction of the specified global element size.
    
20. 
    
21. constraint
    
22. A SymbolicConstant specifying how closely the seeds must be matched by the mesh. The default value is FREE. If unspecified, the existing constraint will remain unchanged. Possible values are:
    
23. 
    
24. FREE: The resulting mesh can be finer or coarser than the specified seeds.
    
25. 
    
26. FINER: The resulting mesh can be finer than the specified seeds.
    
27. 
    
28. Return value
    
29. 
    
30. None
    
31. Exceptions
    
32. 
    
33. None.
